thanks for reply stephen, yep my one is cactus! checked it. Need a new thermostat and o-ring. Gave the question to matt and paul, but they said they only currently had 2nd hand units... Which led me to believe that perhaps unavailable new... ?

Might have to get my "import" shop to try for the parts for me.

Any simple solutions anyone?
